I just checked my friend Myrna's blog and she had a couple of photos of her painting in Spain, so here is how I managed on the streets of Shanghai. I learned to hold all of my stuff and still get a sketch/painting done in 20 minutes. The Chinese people were fascinated, reassuring and friendly.
I am the author of Master Disaster, 5 Ways to Rescue Desperate Watercolors. Based on a course that I have developed over many years, the bones of this book give you a plan to finish your paintings--and even your bombs. The meat of my book and course, though, is to help you structure your life to encourage and accommodate painting. Painters have to paint. This is how to do it.
